Hairy cell leukemia (HCL) and Merkel cell carcinoma (MCC) are two rare malignancies with distinct cells of origin. HCL is a lymphoid malignancy of mature B cells, and MCC derives from neuroendocrine cell origin. HCL has a favorable prognosis with most patients achieving long-term remission and potential cure.

In 1964, the first human oncovirus, Epstein-Barr virus (EBV), was identified in Burkitt lymphoma cells. Since then, six other human oncoviruses have been identified: human papillomavirus (HPV), Merkel cell polyomavirus (MCPyV), hepatitis B and C viruses (HBV and HCV), human T-cell lymphotropic virus-1 (HTLV-1), and human herpesvirus-8 (HHV-8). These viruses are causally linked to 12% of all cancers, many of which have mucocutaneous manifestations. Read More

Purpose: The aim of the present study is to explore the prognostic impact of a subdivision of pT2 by the depth of invasion into the muscularis propria in rectal carcinomas.
Methods: Data from 269 consecutive patients with rectal carcinoma treated with primary tumor resection and lymph node dissection between 1986 and 2012 were analyzed with respect to locoregional and distant recurrence, disease-free survival, and overall survival. The depth of invasion into the muscularis propria of pT2 carcinomas was categorized by the pathologist into two groups: pT2a, invasion into the inner half of the muscularis propria; pT2b, invasion into the outer half of the muscularis propria.

The existence of dynamic cellular phenotypes in changing environmental conditions is of major interest for cell biologists aiming to understand the mechanism and sequence of regulation of gene expression. In the context of therapeutic protein production by Chinese Hamster Ovary (CHO) cells, a detailed temporal understanding of cell-line behavior and control is necessary to achieve more predictable and reliable process performance. Of particular interest are data on dynamic, temporally resolved transcriptional regulation of genes in response to altered substrate availability and culture conditions. Read More

Background: Studies concerning on esophageal squamous cell carcinoma (ESCC) etiological factors have been done for several decades, however, results reported from various investigations were not consistent. The present investigation aimed to explore the presence of 3 oncogenic viruses, human papilloma virus (HPV), Epstein-Barr virus (EBV) and Merkel cell polyomavirus (MCPyV) in the neoplastic and non- neoplastic esophageal lesions collected from Mazandaran, a high risk area of Iran.
Methods: In total, 168 esophageal specimens (100 with ESCC confirmed diagnosis and 68 without esophageal malignancy) were analyzed for HPV, EBV and MCPyV by Real Time PCR. Read More

BACKGROUND Merkel cell carcinoma (MCC) is a rare, aggressive primary cutaneous neuroendocrine tumor frequently associated with Merkel cell polyomavirus infection. Despite its aggressiveness, a few reports of spontaneous MCC regression have been described in the literature, most of them following incisional biopsy supporting a hypothetical role of surgery-induced inflammation in the process of regression. CASE REPORT We report a case of 69-year-old Caucasian male who was followed for an idiopathic hyper-eosinophilic syndrome. Read More

Merkel cell carcinoma is a rare and aggressive cutaneous malignancy of neuroendocrine origin-an often-missed diagnosis due to the wide histopathologic differential diagnosis of malignant small blue cell tumors. The advent of electron microscopy and immunohistochemistry staining for cytokeratin 20, a shared neuroendocrine marker, greatly improved diagnostic accuracy. Over the past decade, staging, treatment, and surveillance of the cancer have progressed at a remarkably rapid pace. Read More

Background: Merkel cell carcinoma (MCC) is an aggressive skin cancer that frequently responds to anti-PD-1 therapy. MCC is associated with sun exposure and, in 80% of cases, Merkel cell polyomavirus (MCPyV). MCPyV-specific T and B cell responses provide a unique opportunity to study cancer-specific immunity throughout PD-1 blockade therapy. Read More

Although immunotherapies have been employed for many decades, immune checkpoint inhibitors have only recently entered the oncologic landscape. Avelumab is a fully human monoclonal antibody that blocks the interaction between PD-L1 on tumor cells and PD-1 on T cells, thereby inhibiting immunosuppression in the tumor microenvironment and reducing tumor growth. Most early clinical trials of avelumab as monotherapy and in combination regimens were part of the international JAVELIN clinical trial program, which included more than 7000 patients in more than 30 trials with at least 15 tumor types.

The coexistence of Merkel cell carcinoma (MCC) and squamous cell carcinoma (SCC) in the same cutaneous lesion is well known. The pathogenesis is believed to be distinct from conventional polyomavirus-related MCC, and it has a more aggressive course. Metastasis of MCC and SCC to the same lymph node is exceedingly rare with only one previously reported case in the English literature. Read More

The cellular origin of Merkel cell carcinoma (MCC) is controversial. We previously hypothesized that MCC originates from hair follicle stem cells or Merkel cell (MC) progenitors residing within the hair follicle bulge. Examination of three cases of combined MCC led to the unexpected discovery that numerous keratin 20 (CK20)-positive MCs within the squamous cell carcinoma (SCC) component of combined MCC appeared morphologically normal with dendritic and oval shapes.

Nonmyeloablative allogeneic hematopoietic cell transplantation (HCT) can provide prolonged remissions in patients with advanced B cell lymphoma (B-NHL) via the graft-versus-lymphoma effect, although inferior results are seen in patients with chemoresistant, bulky, or aggressive disease. Radioimmunotherapy can safely induce responses in B-NHL with minimal nonhematologic toxicity. Initial results of Y-ibritumomab tiuxetan-based allografting demonstrated early safety and disease control in nonremission patients but with short follow-up. Read More

β-Sitosterol (β-Sit) is a dietary phytosterol with demonstrated anticancer activity against a panel of cancers, but its poor solubility in water limits its bioavailability and therapeutic efficacy. In this study, poly(lactide-co-glycolic acid) (PLGA) and block copolymers of poly(ethylene glycol)-block-poly(lactic acid) (PEG-PLA) were used to encapsulate β-Sit into nanoparticles with the aim of enhancing its in vitro anticancer activity. β-Sitosterol-loaded PLGA and PEG-PLA nanoparticles (β-Sit-PLGA and β-Sit-PEG-PLA) were prepared by using a simple emulsion-solvent evaporation technique.

Epithelial-neuronal signaling is essential for sensory encoding in touch, itch, and nociception; however, little is known about the release mechanisms and neurotransmitter receptors through which skin cells govern neuronal excitability. Merkel cells are mechanosensory epidermal cells that have long been proposed to activate neuronal afferents through chemical synaptic transmission. We employed a set of classical criteria for chemical neurotransmission as a framework to test this hypothesis. Read More

Background: Human papillomavirus (HPV) is recognized as an important risk factor for laryngeal carcinogenesis. Although HPV-16 and 18 have been strongly implicated, the presence of other high-risk HPV (HR-HPV) genotypes or the coinfection with Epstein-Barr virus (EBV) or Merkel cell polyomavirus (MCPV) may increase the risk, but their etiological association has not been definitively established.
Methods: We characterized the genotype-specific HPV and the frequency of EBV and MCPV infections through the detection of their DNA in 195 laryngeal specimens of squamous cell carcinoma (SCC) histologically confirmed. Read More
